The problem here is that "Ah" (ampere-hours) is not a unit of energy. To convert that to units of energy, you need to multiply by the voltage of the battery. The result, of course, will vary depending on the battery type.The result of this multiplication would give you ampere-hours-volts, or watts-hours (watts times hours). Therefore, you can then divide by the number of watts used, to obtain the time (in hours).

Is it all right to replace a 12v 4.5ah battery with a 12v 4ah battery in UPS?
I'll answer my own question since no one answered it. I replaced the 2 pcs. 12v 4.5ah battery w/ 2pcs. 12v 4ah battery. It seems alright since it is now working fine for at least 2 months w/ 1 PC connected to the UPS. What I'm concerned though is that the UPS will overcharge the batteries since the replacements have a lower ah rating. --------------------------------------------------------------------------------------------- The charging will be fine - it is how long the UPS will run for (if you mains cuts out) that has been affected by your replacement.
